Ok an update.

Created VM installed Electrum.
Then i moved Private key to Electrum. Total balance is available as predicted (Yeaaahhhh, pfff that's a relieve)

A used the option "pay to many" in Tools, that's a bit scary with comma separation functionality but works like a charm!
Finally I let Electrum  suggest the fee. It estimated that the Tx should be confirmed in about 5 blocks (should be 50 minutes right?)
Tx send to the network at 23:29.

This is the id:
e68efb8fdf5e7d068014fe3d1244ba1ad8f55068c63fb7993ff824b0b9dc7814

But  9 hours later... no confirmation, still not enough fee? The fee was 0.001, can I speed up the TX by using "Child pays for parent" option in Electrum ?
I kind of want to get this over with...


Yeah you were right the total was +/- 2.9. But the total shown in Bitcoin Core was 2.88 (it already deducted the 0.05 TX)

Only the  first two TX in Bitcoin Core where confirmed, the last one was (and is still) unconfirmed, it shows a question mark to the far left.

Well i guess i am one step further but not totally there yet...

Kind regards Peter
